. To all whom it 'may concern:

XVALDo C. Gonoox, a citizen of the United States, residing at Boston, inthe county of Sutl'olk and State of Massachusetts, have invented new anduseful Improvements in Screw-Drivers, of which the following iS aspecification.

This invention relates to screw-drivers. More particularly it relates toScrew-drivers adapted for turning a screw which is set in a. position towhich access by a tool held in the line of the axis of the screw isditii# cult, or Set so that a half revolution cannot Be it known that I,

-be attained by one stroke of the screwdriver. i Y

It is the object of the invention to ine prove upon devices heretoforeknown for this purpose.

It is also 'an object of the invention to produce an improved toolhaving the other advantages of that herein shown and described.

In' the accompanying drawings, which illustrate an embodiment of theinvention,l

Figure 'l is a side elevation of the tool; Fig. 2 is a plan; Fig. 8 isan end elevation; and Fig. 4 is an elevation in section on the line 4 4of Fig. 2.

In a. preferred embodiment of the invention the entire tool may be madefrom a single piece of met-al in which` as repre- Sent-ed in thedrawings, there is a shank or body portion 10, which constitutes thehandie. There is at', one end of the handle a head l1, running acrossthe handle and having two bits l2, lI-l, integral therewith; and thercisatthe other end of the. handle a bit arranged in the line of the handleand constituting an ordinary screw-driver. '.lhe head 11 may beconsidered as a broadened continuation ot' the handle at an anglethereto. Tho edges of the blades or bits l2, 13, liel in the same planeand this plane is so related to the handle that the line ot tho handlemakes an angle of 45 with the plane asshown in `Fig. 2. The bits edgesare pre1'- erably parallel to each other` and conse quently arehorizontal when the handle is horizontal as shown in Fig. l, on oppositesides` of the handle..

W ith a tool constructed as thus described it'. is possible to reachinto a corner and turn a screw set so close therein that it cannot. beengaged byl a screwdriver held in the 'ha-nd vertically above it in theordinary way,

and where there is not room to make a half turnJ at a stroke. I

The operation is as follows: Holding the implement in the hand, one ofthe bits-1s inserted in -the slot in thescrew and the handle is turnedas fai.' as possible. `rlhen the bit is removed from the slot,'and whilerernoyed the implement is lturned about the longitudinal line of thehandle as an axis, and is also swung back toward the other wall, turningabout the axis of the screw. The first glotion described iresults inpresent-ing tothe screw the other -bit at the head end, with its edgerunning at right angles .to .the line'in which the slot was leftbythefirst bit. The' second described movement, in which handle swings backto ,the other wall, turns the bit 90. vIt can .then be engaged in the'slot. The working stroke Atl'nin occurs, the implement being swung ,asfar as it can U0 about the axis of the screw. I screw 90, assuming .the4corner to bea right angle. By .repeating this operation 'the screw maybe turned in successive strokes ot'. 30 each. This operation is ettectedwith a convenience .not heretofore ,-known, for the motions describedare such that' the tool is held conveniently and continuously in thehand, without removingthe heed of the instrument fromthe'immediatevicinity of the head of the screw. In that way no manipulation ormovement is required in addition to the normal movement required forrotat in er the screw, excepto simple and easily ,ellen-ted rotation ot'the tool on its own handle-axis duringthetime -whcn it is inomentarilylifted from the screw --head in order to get a vresl'rhold.

'.lhe. formation of the tool in the peculiar shape shown, in whirh thereis n relatively long straight handle with a head at one end rn'ojectingat right angles thereto in both directions, and with a bit project-ingIfrom the handle at the otherrnd` makes a tool pei'zuliarly adapted foruniversal use as a screw-driver. When used to drive screws in theordinary way, thehead ll is held in the hand, the bit. is applied to thescrew, and the head furnishes a broad and convenient grip and rest. onwhich the palm otl the band may press. to torce the screw with the fullpressure desired; while when used forserews in the cxtram'dinarysituations above described, in which the head- 11 is n otheld in thehand, the end ltwhich is held in or near roo the. palm of the hand,having no projections, presents no obstacle to free and easy rotation ofthe tool on the aXis of its handle Whileheldixlthehand.

I claim A screw driver, comprising a bar havingv at one-end abit-edgefadapted toengage in the slot of a. screw andextendingperpendicular tothe longitudinal dimenslon of the bar; havingat the other end ahead extending perpendicular to the longitudinaldinnension of the bar, said head having two bit-edges on opposite sidesfof said bar, each in plane parallel lo Said longitudinal dimenslon oftllebar and both in a single plane makingAforty-ive degrees angle wlthsaid lon `tudinal dimension of .the bar; the said hea lying in the lastmentioned plane and forming a' handle by which the said bit-edge may beturned. 1 Signed by me 'at Boston, Ma'f' 's 10th WALDO C.
